Open Plan Wood Flooring London

One floor, running without a break from the front door to the garden doors, is what makes an open plan space read as one room. Here is how we get it right through old and new, across changing subfloors, and in the right format for the scale.

01

Matching new to what is there

One continuous oak floor running through connected rooms

The conversation we have most often is about continuity: running one floor from the existing house into a new extension, or matching a knocked-through ground floor to the room next door.

An exact match is not always possible. Products change, batches vary and the existing floor has aged. We compare samples against it in your own natural light, because light decides whether a match reads as one floor or two.

Where a match cannot be made, the cleanest answer is often to lay both areas in the same new floor. Where the existing floor must stay, a well-placed threshold is usually more honest than a near-match that draws attention to the difference. We set out both options and you decide.

02

The right board for a big space

Width, direction and pattern decide whether a large floor feels calm or busy.

03

Old timber to new concrete: the join

Where the original suspended floor meets a new extension slab there is almost always a change of level. We detail it before installation day, never on it.

Original house

Suspended timber

We check the existing deck for movement and bounce and put right any boards that need it before the new floor goes over.

Extension

Concrete slab

We test moisture, confirm the underfloor heating has been commissioned and prepare the slab to a flat tolerance before gluing down.

The join

Planned, not improvised

The change of level is resolved with a new deck, levelling compound or a neat threshold, placed at a natural break such as a door frame or structural line.

Common Questions
About Open Plan
Floors

One floor through a whole ground floor raises the same handful of questions. Here are the honest answers.

Ask Us Anything →
Can I run the same wood floor through an old house and a new extension?
Yes. Running one floor continuously from the original house through a rear extension is the best way to unify the space and remove the visual break that a threshold creates. The challenge is usually at the structural transition — the level change between original suspended timber floor and new concrete extension slab. We plan and detail this transition before installation day, never on it.
How do I match new wood flooring to existing?
Matching new flooring to existing is one of the most technically demanding aspects of floor installation. We compare samples against the existing floor in your own natural light, which is the only reliable test. Factors include species, width, grade, tone, finish sheen, and surface texture. In many cases an exact match is not achievable, and we advise on the best available option or suggest laying both areas in new matching material.
Which direction should wood boards run in an open plan space?
Running boards lengthways — parallel to the longest wall or the main light source — is the most common choice and usually the correct one. It draws the eye along the room, makes the space feel longer, and follows the natural grain direction relative to the room proportions. In square rooms, the direction is less critical and can be determined by the entrance point or by the direction that produces less waste.
What width board suits an open plan space?
Wider boards suit larger open plan spaces. A 90mm board in a 60m² open plan kitchen-diner has more joints than the room needs — the floor feels busy. A 190mm or 220mm board settles the room and scales correctly to the architecture. We advise on width based on the actual square footage and ceiling height of the specific space.
What is the best wood floor for a kitchen extension?
Engineered oak in a hardwax oil or lacquered finish is the correct specification for most kitchen extension floors. The concrete subfloor requires engineered construction — solid wood is not appropriate on concrete. All engineered oak in our collection is underfloor heating compatible, which is important as extensions frequently have UFH installed.
